San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.
San Diego Rat Control Tip of The Week
What Equipment Do I Need To Trap A Rat?
Trapping a rat is not as difficult as it seems, provided you have the right kind of equipment. Rats are a highly intelligent household pest with prior knowledge of your unyielding intentions to either get them killed or captured. As a result of this, they will try as much as possible to run for their lives whenever they get the chance to.
For you to outsmart them and make your plans to trap them successfully, you need good quality traps set up at the spot the rats in your house pass through the most and the right process of setting these traps.
Have you decided to trap the rats in your home and you are looking for the equipment to use and the right way to go about this? The first thing you have to do to achieve your objective is to discover the exact routes of the rats in your house. These are the places you will be setting your traps once you are ready to capture them.
After that, the next thing you have to put in place is the right kind for bait. A good bait should help attract rats and not any other pest or animal in your home. If you just chose a random food substance as bait, you might end up trapping the pets in your home instead of the target pest.
After putting all of that in place, the most important piece of equipment you need to trap a rat is a good quality trap. Your choice of trap depends on whether you want to kill the rats with the trap or just trap them and later release them far away from your home.
If you choose to kill them directly with the trap, a lethal rat trap will be most appropriate. The only issue with the use of this trap is that you will have to get multiple traps and set them at different locations because this kind of trap can't trap more than one rat at a time.
On the other hand, if you choose to trap the rats and release them afterward, a one-way entry door trap will also be most appropriate. Also, while setting up either of these traps, you need to protect yourself at all times from the bacteria spread by the rats by wearing a pair of gloves and a protective mask.
